Hardinge FlexC™ Collet Systems are flexible, sealed collet heads that interchange in seconds and are available with spindle mounts for all brands of CNC lathes.
Pull-back thru-hole, pull-back stationary stop and push-to-close dead-length® styles are available for main and sub-spindle CNC lathe applications. Hardinge FlexC collet heads are fully interchangeable with competitor’s models. Hardinge guarantees accuracy within .0004" (.010mm) TIR for the collet system models A and D, and .0008" (.020mm) TIR for style DL.
The changeover concept is simple using a manual wrench to compress the collet for quick removal or replacement in seconds. A typical FlexC collet head has a gripping range of .020" (.5mm) above and below its nominal size to allow variation in bar stock without having to change the collet. Parallel clamping minimizes stock "push back" and requires less draw bar force to achieve the same gripping capability as conventional collets.
Emergency collets are reusable. Standard hardened and ground collets are stocked in round smooth, round serrated and hex shape. Square sizes are made to order. Special applications including stepped holes, special shapes, off-center, etc. can be custom-made from stock blanks.

HSK Tooling Types Offered:
• Four types of MEGA Chuck series optimises high speed and precise cutting with drills and endmills.
• The Fullcut Mill, the world's first indexable insert endmill, offers both accuracy and toughness.
• KAB tool shanks, the original and #1 modular boring system in the world!
Premium Material Selection
Since HSK is a hollow taper shank, the material has a critical role for optimum performance. BIG uses carefully selected high grade alloy steels. Particularly, BIG uses die steel materials for HSK 40 and smaller where the cross section of shank taper is very thin.
Important Tool Retention Feature
Internal clamping of HSK tools is defined by the location of highly concentrated forces from the machine tool. Accuracy and position of this form will affect the righdity, repeatability, and precision of tool holders. BIG provides finish machining of this area after heat treatment.
Drive Key Form
HSK Shanks according to Form A are designed to carry out torque transmission by the round shaped key-way at the end of the taper. Because of the importance of this round shaped geometry, BIG provides finishing of this feature after heat treatment.
Pre-Balanced Design
Since HSK Form A has non-symmetric keyways, it is not balanced. BIG Form A holders are pre-balanced near the tool change V-Groove recommended by ISO standard and can therefore be used for high speed applications.
Hole For Manual Clamping
BIG HSK Form A holders have a manual clamping hole as a standard and can therefore be used in place of HSK Form C which is manually mounted in spindles.

- Every collet chuck comes with our exclusive "Power Coat" nut that holds up to 75% tighter than standard nuts. (greater holding force improves T.I.R., rigidity, and reduces tool slippage to extend collet life)
- Tolerance measured from taper O.D. to collet pocket I.D. is only 0.0001" (our competitors average 0.0002")
- Every collet chuck is lab tested and delivered with a full report documenting T.I.R., balance, taper, etc.
- Our standard precision collets feature T.I.R. of only 0.0004" (our competitors average 0.0006" - you gain 20% tool life)
- Each holder is factory balanced to 18,000 RPM @ G2.5 (great balance reduces vibration at all RPM's - saving toolife, spindle bearings, and improves surface finish)
- Each taper is precision ground to a tolerance of AT3 or better!
- All products are backed by our 100% satisfaction guarantee.
Advantages:
- Flexibility (fits a wide range of tool shanks)
- Accurate (when maintained to specifications)
- Fast and easy tool changes

To achieve best results with centerdrill we recommend the following basic equipment:
1x collet chuck with cooling ring, clamping nut and spanners.
1x centerdrill collet, optional Ø 6, Ø 8, ..., Ø 20mm
1x 250 gr. parting paste for flow punch forming
1x 0,5 l lubricant for thread forming
Due to the extreme thermal fluctuation and the radial load, proper clamping of the workpart and the flow punch former is critical. The warmth generated during the process must not be allowed to enter the spindle but instead must be deflected or cooled. Customary three-part chucks can cause breakage of the flow punch former if it is not clamped centrally!
For this reason a collet chuck with cooling ring was developed especially for flow punch forming with centerdrill, with which the heat can be dissipated ideally and a secure clamping can be ensured. For optimal concentricity and secure clamping, a special collet is used to locate the centerdrill.
Parting Paste
Moistening the centerdrill with our highly heat-resistant parting paste, matched to the respective material to be processed, is important for the service life of the centerdrill. The paste can be applied manually or with a spray device.
Lubrication during thread forming
The use of our lubricant is highly recommended during thread forming. It should be applied before each operation on the center- tap. Our lubricant is ecologically tested according to DIN.

DURO-key bar chucks and plane spiral chucks (DIN 6350 und DIN 6351) are successfully used wherever extremely high tension forces, high concentric accuracy and reliable continuous repeatability are needed. The three-jaw DURO key bar chuck is characterised by its very high tension force and accuracy, which is twice a high as prescribed in DIN 6386. The running and run-out accuracy of our three- and four-jawed plane spiral chucks meets DIN 6386, Part 1, Accuracy Class I. In order to machine large and heavy workpieces at the highest possible cutting capacity, optimum clamping is required using great forces. Röhm plane disks, with a diameter of up to 4500 mm and their indisputable merits have proven themselves here.

F-Tool PIN center chuck
The PIN center chuck is a compact reference system and is able for the collet of electrodes and work pieces. It‘s also the base of the F-Tool PIN ZeroPoint centering system. The centering, respective the positioning happens in two steps. The first step is the pre-centering with the PIN centering bolt. The precise centering is done, if the cone of the spigot is intervening on the flexible centering plate, and the piece is drawn to the clamping area. With the intervention of the PIN index 8 mm into the cross slot, the angle coat is defined.
